How to treat rhinopias with ich?
Rhinopias and all other Scorpionfish are highly sensitive to all copper products; this includes both chelated copper and ionic copper. There are three options for treating ich. The first option is to implement hyposalinity. It’s an innocuous and effective treatment for most saltwater aquarium fish, and rhinopias handle it well. The second potential treatment is the Tank Transfer Method. This process is also safe for your Rhinopias, but these fish are venomous. It seems best to keep handling to a minimum, and the TTM requires frequent contact. Lastly, Chloroquine Phosphate is a safe and efficient treatment for scorpionfish with ich or velvet. CP is the treatment of choice if the ich infestation is harsh (very rare for Rhinopias) or if diagnosing between ich and velvet is too equivocal.

Why are grazing fish attracted to rhinos?
Additionally, algae accumulate on the bodies of Rhinopias, and this leads grazing fish to gravitate towards them naturally. This attraction can cause two potential negative scenarios. First, the Rhinopias may be injured and develop an infection, or, second, the grazing fish may be stung by the Rhinopias’ venomous spines. In most cases, these grazing fish bypass Rhinopias because of their vibrant colors, but aquarists must exercise caution. R. Frondosa (Weedy Scorpion) are most at risk of being nipped because they resemble a rock covered in algae. Sizable wrasse, hogfish, rabbitfish, and other substantially sized community fish will coexist with Rhinopias peacefully in a FOWLR aquarium.
Where do rhinos live?
R. Frondosa and R. Eschmeyeri are endemic to Indonesia, the Philippines, East Africa, Northeastern Australia, and Japan. The majority of their time is spent lounging in the same area waiting for prey to come into striking range. Because of this, algae accumulate on their skin. Rhinopias periodically shed their outer cuticle to rid themselves of external parasites and algae. Some Rhinopias shed as frequently as every 12 days while others may only shed once every six weeks.

What to feed a scorpionfish?
One thing you should avoid is feeding your scorpionfish a diet consisting only of feeder goldfish. Raw goldfish flesh contains thiaminase, an enzyme that causes the breakdown of thiamin. If you feed your scorpionfish a diet that consists only of goldfish, they may become thiamin deficient, which can result in feeding cessation, clamped fins and nervous in coordination. If you have to feed them live food, gut pack mollies, guppies and/or ghost shrimp with a nutritious food (e.g., Cyclop-eeze®) before you feed them to your Rhinopias (some individual may be reluctant to feed on live ghost shrimp).
How big of a tank should I use for rhinos?
I would suggest that a smaller Rhinopias be housed in an aquarium of at least 20 gallons, while larger adults will do fine in a standard 30 gallon tank. Although some décor is needed to help your Rhinopias “feel at home,” do not over do it. These fishes (especially R. eschmeyeri ) often sit in repose on open sand, mud or rubble bottoms. Because these fishes tend to spend most of their time in the open (unlike some scorpionfishes, which are more cryptic) they make an interesting addition to the reef aquarium.
My Own Little World
Rhinopias Basics
- These animals come from several areas around the world, with some hailing from Australia while others come from Indonesia. They are tough to spot, even for a seasoned diver. Their unique camouflage blends in perfectly with the reef and the gentle swaying of the current moves them naturally with their surroundings. It’s this ability to blend in that makes them not only rare in the …
Rhinopias in The Aquarium Trade
- Several species of Rhinopias are occasionally offered for sale, such as the weedy scorpionfish Rhinopias frondosa andEschmeyer’s scorpionfish R. eschmeyeri. The weedy scorpionfish is wide ranging, occurring in locations such as East Africa up through to Japan. Many species that are collected for our aquariums come from Sri Lanka. These fish grow to a maximum size of aroun…
Interesting Behaviors
- There are several characteristics these scorpionfish display that often worry many aquarists. First, they don’t swim much, if at all. They prefer to use their fins and slowly crawl along the bottom. Typically these animals find a comfortable spot on a sandy bottom in the aquarium and set up shop. They rarely move and will sway to and fro in the tank’s natural current, mimicking a strand …
Tankmates
- Those wishing to keep Rhinopias with tankmates should keep in mind four things. Of course these are just my recommendations, but to me it seems to make the tank environment more harmonious. Don’t Forget About the Venom First, like all scorpionfish, Rhinopias are venomous. Luckily they are pretty laid back (at least in my experience) about arming their venomous dorsal …
Other Concerns
- In my humble opinion, the best place for a Rhinopias scorpionfish is a species-only nano environment. You read right, a nano environment. Small aquariums of 20 to 30 gallons work well for this species. While they grow moderately large, they barely move and require little space. Small nano aquariums can also really simplify feeding as well, since the animal usually won’t chase do…
Final Thoughts
- Rhinopias scorpionfish are bizarre, rare, and exceptionally magnificent aquatic predators. They quickly become living conversation pieces and many non-aquarists are shocked to learn that this unique animal is actually a living fish. Even though Rhinopias have some different and unusual care requirements, once acclimated to the aquarium they are very hardy and easily kept, given th…

Keeping Them in Captivity
- All the Rhinopias readily adapt to captivity and because of they are relatively inactive they can be kept in smaller aquaria (Dinesen and Nash 1982, Howe et al. 1988, personal observation). I would suggest that a smaller Rhinopias be housed in an aquarium of at least 20 gallons, while larger adults will do fine in a standard 30 gallon tank. Although some décor is needed to help your Rhin…
Behavior
- Hepatic lipidosis, or fatty degeneration of the liver, has been reported in a scorpionfish fed only fresh hake. This condition can cause liver failure, which leads to suppression of the immune system, hemorrhaging and anemia. Lipidosis is best avoided by giving your scorpionfish as varied a dietas possible and by not overfeeding. I would recommend ...
Acknowledgements
- I want to thank Dennis and Eric Reynolds (Aqua Marines), Randy Walker (The Marine Center), Jim Walters (Old Town Aquarium, Chicago) and Julian Sprung for helping me acquire Rhinopias over the years. Mitch Carl (Omaha Henry Doorly Zoo) and Jim Walters shared some of their observations on Rhinopias frondosa (if your in the Omaha area, you should go see the beauty at …
